tion upon the Sectio-ns of Fig-[26 by the neck former mechanism in the machine as disclosed one side beingequipped to form the closed :vends-of ed vials after acscrew' neck vials andthe other side equipped y The 'machine `may ,bef continuously driven by the belt- 1, shown in Fig. 1 as on the loose pulley 2 'carried the shaft 3. s

When this driving belt 1 is shifted to the fast pulley 4, the'shaft 3' is driven toactuate the worms' 5, 6; The worm 5 drives the worm 'wheel 7' on Athes'haft 8 `(Figs. 1

and 8). Fast on the shaft 8 are the sprocketv wheels 9 over which pass the sprocket chains -or conveyers 10. r1 he shaft 8 is lmounted 11 l.carried by the main in thev bearings frame 12. Atthe remote'end of the frame 12 from the shaft; 8 are bearingsll carrying the .shaft 13 upon which is, mounted the sprocket wheels 14 over` which vpass the sprocket chains 10 having the roller flights 1 5 forin-l ing anti-friction ware holder s.w' l'1lhe bearf sprocket wheel 18 thereon driving'sprocket chain 1-,9 extending over the sprocket wheel 21. The slack in this sprocket cha-in is taken' up by the adjustable idler 22. This shaft 21 carries sprocket wheels 23. 'The shaft 21 is mounted in the bearings 24 carried by the frame 12. The bearings 24 also carry adjustable bearing brackets 25 for the shaft 26 carrying a pair of sprocket wheels 23 similar to the pair of sprocket wheels 23 on the shaft 21. Over these sprocket wheels pass the sprocket chains 27 embodying` the guide blocks 28 (Figs. 5, 9) through each of which is reciprocable a rectangular nonrotatable element 29 having roller l30 mounted on the pin 31 extending into the element 29 from the inner end of said element so that said roller 30 may vfreely rotate, as by contacting the end of a rotating blank, thereby taking retarding friction ofi said blank when the face of the roller 30 is moved thereagainst by the action of the member 29 through. its guiding roller 32 coacting with the cams 33. The cams 33 first move the disks 30 into contacting relation with the ends say of a rotating blank.

vIn the manufacture of vials, a cylindrical tubular section of glass may be put between the guide plates 34 (Figs. 1, 5) to rest in an anti-friction holder 15 on each of the conveyers 10 to be carried by .said conveyers under the bars 35 (Fig. 11) which are adjustable in the brackets 36 and carry the yieldable, contacting member or soft rubber 37 directly opposing the anti-friction holders 15 of the conveyers or sprocket chains -10. As the sprocket chains travel the blank or ware contacting the rubber or stationary pressure bar 37 1s caused to rotate. Adjustment up and down of the elements carried by the brackets 36 cares for different diameter tubing for vials, while adjustment of the longitudinal beams of the frame 12 toward or from each other permits length variation in vials. Y

The motor 38, (Fig- 1) through its belt 39 drives the fan therefrom (Figs. 1, 5, 11) to the iiuid discharge means 42 which have upwardly opening outlet slots parallel with the machine way orline of travel of the war Between these air discharging passages is mounted 20 fast on the 'shaft Vthe burner 43 having a discharge slot u wardly directed and parallel with the slots 42. The bolt 44 through the slotted plates adjustably mounts the burner 43 as to the machine frame 12 so that vertical or lateral adjustment may be had (Fig. 12).

This action of the burner on the blank serves to heat the blank and this heating or 40 having duct 41 leading production of hot ware is maintained local to' the Aportion directly above the burner 43 by the action of the-air blast 42 directed upward. The air on each side of the heated portion thereby provides on each side of the jet, protecting the moving parts of the holders 15 and conveyers 10 as well as the rubber contacting members 37.

Asthe blank becomes heatedcentrally, in order to avoid thickening, the blank may be elongated by moving the sections transversely of their line of travel as to the way in the machine. This is accomplished by the driving belt 45 driving the' pulley 46 on the shaft 47 mounted in the adjustable bearings 48 carried by the frame l2. The shaft 47 (Figs. 1, 5) has the oppositel'y disposed spiral gears 48 coacting with the spiral pinions 49 on the shafts 50. These shafts 50 (Figs. 5, 11, 12) carry the ware contacting rollers 51 which may also be of yielding maa cooling blanket terial to better engage the ware, such material in the disclosure being rubber. These rollers 51 rotate positively with the under portions moving out as shown in Fig. 12 so that in contacting the ware or blank such blanks are thrust against the disks 30 when the rollers 32 of the elements 29 bear against the adjustable cam portions 52 and thereby gradually elongate the weakened central portion of theblank to assist in reshaping or severing as said cam sections are adjusted to the desired pre-determined extent. The rollers 32 are then urged inwardly by the adjustable cam portions 53 (Fig. 5), which inward travel is permitted by the idle rollers 54 similar to the live rollers 51. As the blanks pass the rollers 51, 54, they rotate on their own axes as well as have transverse actuation. Upon leaving the rollers 54 the blanks again are rotated by the pressure bar or contacting members'37 and abut adjustable end guides 55 to determine their position.-

The sheet air jets or fluid discharge means 42 extend to the region of the rollers 51, 54. To provide a means for counteracting any heating of these rollers as well as deterioration of the rubber thereof, the duct 56 from the fan 40 conveys fluid to the roller jacketing members 57 (Figs. 1, 5, 12) which jacketing members 57 provide passages for a continuous current of cooling air closely adjacent a side of the rollers. These jacketing members 57 have fluid discharge openings 58 upwardlydirected, one on each side of the plane of the burner, current inciting means not the heat of the burner only to confine but qulckly remove -such heatfrom the machine by upward curwhich serve as ducts 60 (Figsl, 11) in communication with .being a disk directly registering with` the fluid passa es 61 adjustably supported with the bars 37 by the brackets 36 and extending parallel with the way or line of travel of the conveyers. (Fig. J1) serves to carry away the heated water and thus complete the circulation of the liquid through the machine.` v

The cams .63 (Fig. 5) serve to withdraw the membersv'29 so that they are in position to be acted upon by the cams 33 when they complete their circuit of continuous travel in synchronism with the holders 15, there each of 'said holders in its travel past the cams 33, 5e, 53, 63.

This drawing apart of the blanks during the continued heating thereof effects aseparation' of the blank into two sections, and a rounding ofi' or flowing of said separated sections to a closed end form.

In the production of bottles or vials it is desirable that the closed end or bottom. be shaped flat in many instances. To care for this positively a bott-omingdevice is introduced. Fast on the shaft 17 lis the toothed wheel 64 (Figs. 1, 2, 5) timed to have its teeth in synchronism with the ware holders 15. Thellever 65v mounted on the fulcrum 66 has pin 67 hriding on the 'teeth of, the wheel 64. to rock said lever against the counterweight 68 and thereby through the adjustable link 694 coacting with the arm 0 rock the shaftl 71 (Figs.2, 3, 4). This shaft 71 is maintained against lateral movement as tov its bearings 72 by the collars 73 theld by the setscrews 74. Intermediate these bearings 72 f threaded portions 75 upon which are mounted the bushings 76 and as toI which the yokes 771 are held by the` set screws 78. @These yokes .7 7 carry the formers,bottoming pad dles or plates 79 and the yokes are' held.` -from rotation by the i therethrough parallel with the shaft 71. As

occur just as the pat of the shaft 71 is rocked by lthe lever 65 from the wheel 64, lthe plates or paddles 79 simultaneously move apartand then quickly re.Q turn` to their` central orl closed position. This quick separation movement is timed to plastic bottoms are in position as'to theJ bottoming'elements 7 9 and thereac'cordingly results in the outward movement a gentle shortv duration which forces the closed end of each blanksection .into a plane insuring a flat bottom for each article.

The. severed and completely bottomed blank sections now contact at their inner -Ien'ds the central adjustable dividing member' 'or tongue. 81 (Figs. 5, 13) which is heated by the burner 82; as controlled'by the Outlet duct 62 adjusting bolts 44.

blank sections lwith the valve 83. The'heating of this tongue 81 i cooling of the next burner section 85 for still less heating than the burners 85 and 82 (Fig. 8).

This tongue member 81,/ gradually wdrks the blank sections away from eachother and l during this travel the outer ends are heated by the long narrow dThis warming or reheating relieves local strains in the formed bot- These burners 87 have their exhaust taken up by the Jiues 88 thereover and the heating action of these burners may be confined tothe outer end portion and kept the holder thereby supplementing the cooling action of the liquid circulating passage 61. Further, the fluid duct 89 conveys air from the lfan, 40 to the fluid dischargmg means 90 parallel with the conveyers 10 as izing the lheating action. The burners 87 may accordingly diverge to `allow for the transverse travel ,of the blank sections as produced by the central, bottoming memberv 81. The'flues 88 are removably mounted upon the machine by the angle ongue 91 engaging in the brackets 92 (Fig. 13).

' Fast on the shaft 8 (Figs. 1, 8) is the sprocket wheel 92. having the sprocket chain.-

burners 87 mounted onl an additional feature for localreciprocable members 29 carrying the transverse actuating `rollers 32. -The `inward re- 29 carries the cessed end of the member spring 99 against which the bearing stem 100- is held by and the centering element l103( are non-rotatably held by the nonA-rotatab e the pin 101fso that-the collar I The heated outer en`ds of theblanks passing the burners 87V are brought to a plastic state as' the burners arey adjusted by the the sprocket chains 98 passing over the ,sprocket wheels 106, 97, i bringin synchronisln the centering'element 103 for ea h holder 15 so that ,each article of Ware may have the centering element 103 properly linedup therewith and' hold such article during the lip or neck forming op: eration.

The driving pulley 107 -A(Fig. 8) serves to drive the shaft 108 having the universal as to the holders, as does the o connection 109 (Fig. 7) with the shaft 110 connected to actuatethe pulleys 111 carrying the belts 112 passing over the pulleys 113 (Fig. 8) having the bearing block 1141l pro- -.vided with the liquid-chamber to which extends the water supply .duct 115 and from which extends the water exhaust 116. The adjusting nut 117 serves to of the vbelts 112.I These belts have ayieldable jfacing as a contacting member, say of rubber. 'These belts are driven in thedirection of ware travel so that the warel is readily brought thereunder when it approaches the belts and the speed is such that for this short duration of tlmela high'rotative velocity is given the ware and this rotative velocity occurs, while the centering means 103 K is in active position as also during the neck or neck and lip forming operation.

Mounted inI the frame 12 adjacent the' pulley 113 `iss-the bracket 118 carrying the upper member 119 yieldably held by the springs 120 to carry the upper neck` 121 (Fig. 1 4) as a non-traveling member, while' the centering element 103 may pass therebelow inserted Ain the blank. Opposing this upper neck forming member 121 may be a similar lower neck forming member 121 also lheld yieldably in position by spring120 'acting uponv the` lower hinged member 119. The device of Fig..15 showsr the spring 120 yieldably-holdin g the' hinged member 1,19 agamst the collar 102 of the centering blade p or element 103 whilethe actual neck forming is accomplished `by the single lower neck forming element 121 rigidly held in the hingedl member 120 by the bolt 122, in definite adjusted position and stationary while the traveling ware passes along.

The centering elements are controlled by y the adjustable cams `123 timed tocoact withY the rollers 32 to insert the bladed centering elements 4103 inthe blanks as the blanks approach the vhigh speed rotating device or belts 112. `These l,centering elements are withdrawnv by the positively directing cam.l

This device (Figs. 1, 6, 7) embodies a coil` 125 upon aiiexiblestem 126 and extends adjacent the rollers 111k to yieldinglyengage 15. f The vials in assing alonsg under the, spiral 125 are dellver'ed thereby to the Ilexible tape 127 yieldinglyv` held thereagainst by the springs 128 to pass the completed ware to the chute 129., The extension 130 from the bearing-l 131 carrying pulleys take up 'tension former* 117 and bythe bearingI In the lip Lforming device of Figs. 14, 15 l there' is relative rotation between the blank being reformed and the exterior forming or shaping element as well as the interior forming or shapingelement. In some instances itis desirable to produce a form which is not the form 'of simple revolution. A usual type thereof is a screw neck construction in thejproduction of which threading the eX- terior forming element coacts with the blank without relative movement.

'A bracket 118 (Figs. 17, 18) has hinged thereto the members 132 with the set screwsA 133 engaging therewith to maintain the members 132 in parallel relation notwithstanding they 4are mountedl on the pivot pins 134. To preclude any outward swingof these members 132 the supplemental arms 135 are provided and their set screws 136 may lbe adjusted to nicely regulate the outward limit for the mem-bers 132. The lower member '132 carries the threaded follower roller 137 which in being contacted by the plastic end of the rapidly rotating ware forms thereoma threaded extension. For threading the roller is shown with such form therein. Opposing this roller 137 is a second follower roller 138 simultaneously driven.

The narrow edge of this roller 138 extends to,

the root of the threads formed by the roller 137 at the'shoulder end thereof and defiunit/ely shapes the shoulder so that it mayreceive a gasket, if desired. This roller 138 `may be'wider to define a neck or neck andk *lip when the outer threading is'omitted.

The actionjof the collar 102 issuch that the outer end of the threaded portiony of the article is in a plane. With such an article a'screw cap may effect sealing by a packing either at'the shoulder or in the-cap.

Supplementing this closure structure of extenio'r threading, there may be an interlor threading. NInstead of the bar 29 carrylng the blade` element 103, there'is the stem 139 (Figs. 17,19) having the fpins 140 therethrough, so that when the cam 123 thrusts the bar 29 into the plastic end of the ware, this pin 140 is unseated from the transverse "mlot or recess 141 in the spool A142, thereby v released for free rotation as to the pin 140, and the/elements are in the position shown in Fig. 17. Action of the cam 124: in bringing the pin 140 into the recess 141 at once keys the'externally threaded spool 142 "and insures its immediate hexpulsion by the rotation of the newly formed interior thread pressed thereon by the .outside rollerafter the spool has entered the plastic end of the ware. Each carrier may-coact with an article of Ware inI each of its4 cycles of travel the-'distance apart of which may blank sections .146,

thereby continuously producing articles with great rapidity and of uniform character.

In the operation of the machinev a 'length of tube of the desired dimension is placed between the lrelatively adjustable plates 34 by the setting of the brackets in' the main frame 12.y This blank 143 l (Fig.l 21) 1s heated and elongated'to produce the blank 144 (Fig. 22) ywhich is theform of the vblankas handled by .the transverse actuating rollers- 51. At this step the heating of the elongated blank 144 results in the production of theblank sections 145 (Fig. 23) which blank sections have the pointed closed inner ends. Continued heating of these` ends by drawing them in closer to the burner 43, as effective by the cams 53, Hows .these inner ends to'v a more abrupt or approximately ilattened portion, as shown inthe (Fig. 24). This flatten-l ing is comple ed by the'bottoming device blades 79, producing` the blank sections 147 (Fig. 25). While the formed bottom is bes in gradually cooled by the member 81, wich is also transversely actuating 'the blanks as to the way, or moving them'outward, there is a' heating of the outer ends of said blanksby the thej blank sections 148 (Fig. 26). These blank sections which have been rotated up to this point solely by the opposing contacting Y bar 37 or transverse actuating rollers 51, are now speeded up by the belts 112, as the non-rotating centering loladel1034 or Stem 140 with the spool-142 enter such plasticends andthe collars 102 abut said ends. These care for `the forming of the neck insides'and'the endsof the vial` opposing the bottom. Y `Simultaneously withthis action, the iXed or non-traveling neck former 121 of short( upon` one side only longitudinal extent and of the blank completes the groove or neck to finish` the vial 149 (1|`ig..27) or thev rollers 137, 13S-form the screwthreaded neck of the vial 150 or. 151l (Figs. 20, 27).
